"Whenever you come to an away venue and have conditions like that with an opposition having had that sort of loss the week before, you know it's going to be a bun fight," Voss said.

"For us to come away with a win from that was enormous especially in the circumstances of having two guys go down. We just had to tough it out and the guys did that amazingly well.

"He's (Brennan) done an ankle, but we are hoping it's only a slight tweak. His (Bradshaw) is a slight hamstring and that could be just one week, it's not a long-term one."

Fremantle coach Mark Harvey acknowledged his team's better effort, but is lacking the class to get the ball inside-50 enough, or to capitalise when it is in there. The Dockers went in their 50 just 34 times to Brisbane's 62 for the game.

"It was a pretty good effort from our guys. We are lacking class at the moment in the midfield and forward line. If you have 30 less entries you are missing class along the way when there's not a lot in the total disposals," Harvey said.

"What we are finding as a regular pattern is that we can be there in most games at half-time and then we fall away. That is a combination of a lot of things, but a lot of that is that we don't have enough seasoned players at the moment."
